Why execute cats groom each other? The answers can surprise you: It’s not always about hygiene or even affection. Cat as a species participate in society grooming, also known together allogrooming. Let’s explore the various reasons why cat groom each other—the good, the bad, and also the ugly.

Why execute cats participate in allogrooming?

Allogrooming refers to social grooming in between members of the exact same species. Countless species, including primates, birds, and even insects, groom each other as a means of bonding and also reinforcing social hierarchies.

Allogrooming in cats have the right to be finest observed in free-roaming cat colonies. A 2016 study released in the Journal of vet Behavior found that “allogrooming is just one of three methods cats to express cohesion in colonies. The various other two ways are allorubbing and transmitting scent signals.”

From observations of cat swarm allogrooming, scientists have actually been able come conclude the following:

While 2 cats might regularly connect in allogrooming together, one cat will commonly give the majority of the grooming.Dominant, confident cats are more likely to allogroom less-dominant, less-confident cats.Cats commonly receive more grooming from cats that space aggressive toward them.Two conditions co-relate with much more allogrooming: higher numbers of bag of cats living in the very same space, and also less aggressive actions between cats.

Domestic cats aren’t the just felines to participate in allogrooming. Scientists have studied this actions in lions and other large cat colonies.

Fascinating finds

Blogger KittyClysm recently gathered a comprehensive set of research study on why cat groom every other. Many of she data was pulled native a 1998 study published in the Journal of Ethology. The study centered roughly 25 adult cat living in confinement—14 male, 11 female, every neutered or spayed.

Some of the fascinating insights traction from the study incorporate the following:

Of the allogrooming sessions, 65.1% were between two males, 31.3% to be males with females, and also only 3.6% were two females together. Male cats virtually always (90.4%) acted together initiators.The vast bulk of interactions (94%) began with one pet approaching or inviting the other animal—not when animals were already sitting or lied together.The majority of interaction (91.6%) to be unidirectional (one cat licked and groomed the other).Allogrooming usually arisen in the head-neck area.More regularly (78.6% of the time) higher-ranking cat were the ones that groomed the lower-ranking cats.Whether cat were blood loved ones did not impact frequency or term of allogrooming sessions.

So, why do cats groom each other?

With these monitorings in mind, animal behaviorists have narrowed under several reasons why cat groom every other. Because that instance, the author of the 1998 Journal that Ethology study provides his own theory:

The author posits the “domestic cat allogrooming is most likely a way for cats to redirect pent-up aggression and to reaffirm prominence in a method that’s far better (for the group) than doing so v aggressive and even violent behaviors.”

This theory makes complete sense in the context of free-roaming cat that must abide by society hierarchies in stimulate to endure in the colony. Yet what about cats living the an excellent life with each other as at home pets?

Social bonding

As miscellaneous studies have observed, allogrooming occurs among cats that currently have a social bond. If a pair of indoor cats typically accept each other, castle are an ext likely to interact in this kind of social grooming.

Social ranking

Often times, the dominant cat in the family will groom the others as a method of reinforcing his position in the hierarchy. You might even notice one the your cats (typically the submissive or “lower-ranking” cat) soliciting allogrooming by draw close the leading cat, flexing his neck, and also exposing the height of his head or earlier of his neck.

Familial affection

Although the 1998 study uncovered that “allogrooming does not seem to have anything to perform with whether cats room siblings, parent-and-child, cousins, or relations of any type of kind,” there is many of anecdotal evidence of the bonds formed in between cats of the exact same litter, a mom cat and her kittens, and also more. This might only come right into play among domesticated cats—feral cat swarms are far less most likely to present loyalty come bloodlines.

Why perform cats groom each other? The price isn’t exactly straightforward. Us now recognize that restroom doesn’t usually play a role in allogrooming—instead, this behavior can be seen as social acceptance and also even supremacy in the context of the group.
